UNITED STATES PATENT OFFICE.

JULIUS LOEB, OF NEW YORK, N. Y.

THREAD-DRESSING MACHINE.

Specification of Letters Patent No. 29,981, dated September 11, 1860.

To all whom "it may concern:

Be it known that I, J ULIUS LOEB, of the city and State of New York,have invented, made, and applied to use a certain new and useful Machinefor Glazing Thread and Twine in Skeins; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand opera tion of my said invention, reference being had to the annexeddrawing, making part of this specification, wherein- Figure 1, is afront elevation of my machine, and Fig. 2 is a side view, of the same.

Similar marks of reference denote the same parts.

My said invention relates to mechanism by which skeins of silk, cotton,linen or other thread or twine are subjected to a polishing operationfor the purpose of glazing the same.

My invention is distinguished from the mechanism heretofore employed forglazing spool thread before winding. That mechanism not being adapted tooperation upon skeins, has to a considerable extent prevented theintroduction of glazed skeins of thread, while the spool cotton isalmost all 110w glazed before winding.

My invention also differs from the mechanism heretofore in use forglazing skeins of thread, and consists in revolving brushes and groovedribs or flanges that act conjointly to brush and glaze the threads atthe same time that the grooved flanges open, loosen, separate and turnthe threads around so that the brushes operate uniformly on all sides;and the current of air produced by these revolving brushes also tends todry the threads as they are glazed.

By my machine I am enabled to glaze the threads composing the skein in abetter and more speedy manner than the threads when glazed previous towinding, because I not only loosen and separate the threads of theskein, but apply sufficient tension to said skeins to stretch the sameand compensate for shrinkage in dipping said skein into the materialused for glazing.

In the drawing CZ, a, represent a suitable framework carrying the brushZ), that is to be revolved by suitable power.

0, is a roller set in open bearings 1, 1, and driven by a band, gears,or other mechanism from the brush shaft (6).

(Z, is a roller set in journal boxes 2, 2.

The skeins after being immersed in the composition used for glazing, arehung over the roller 0, and the roller (Z, entered through said skeins.The journal boxes 2, 2, guide this roller (Z and keep the same in place,and the weight of the roller (Z, tends to keep the skeins stretchedtightly, but if this is in sufficient, screws are to be applied to drawdown the journal boxes 2, 2, and tighten the skeins. Upon power beingapplied the skeins revolve slowly with the rollers 0, (Z, while thebrush 1) revolves with a rapid motion against said skeins as presentedby their revolution to its action. This opera tion glazes the thread asthe composition with which the skeins are'moistened dries. It is,however, important that the brushes act all around the threads of theskeins to glaze all sides equally, I therefore introduce the flanges e,6, between the brushes Z), Z), in the edges of which flanges diagonalgrooves are introduced as seen in Fig. l. The edges of these groovesmust be rounding and all the parts very smooth so as not to injure thethreads. It will be evident that in the revolution of the brush thesegrooves in the flanges tend to spread the threads in each skein and turnthe separate threads around so that all sides of each thread are equallyacted on; and the glazing is uniform and perfect.

One or both the rollers 0, (Z, may be heated to aid in drying theskeins, and the skeins may be larger or smaller in size, or in the formof large skeins or hanks.

I do not claim glazing skeins of thread &c. as mechanism has before beenemployed for this purpose, but the same tended to iron or compress andflatten the threads and did not act to separate the threads and brushthem equally on all sides, therefore and I do not claim a revolvingbrush nor grooved rollers or ribs in themselves as these have beforebeen used in dressing threads.

hat I claim and desire to secure by Letters Patentis The diagonallygrooved flanges or ribs 6, e, on the revolving brush to separate, loosenand spread the threads composing the skeins, so that the brushes Z), mayact equally on all sides of said threads to glaze the same, as setforth.

In witness whereof I have hereunto set my signature this seventeenth dayof May 1860.

J. LOEB.
